Plug the fuel hose and fuel tap vaccum hose, which go the carburetor. Wash with water. There is a Water Drain Hole, just below the thermo-stat Elbow, on the R.H. side of the cylinder head. Chase a piece of baling wire / mechanics wire UP thru it.
Water, scrub, water, compressed air. Get the MUD out. Then loosen the plug, just a Half turn, Spray with carb cleaner / brake cleaner and use the compressed air one more time.
Be certain to Dry out the Inside of the Spark Plug Cap.
